Terminal entry not found with "tmux-256color" #21

Hi! My error said to come report this:

Version: 0.9.18
LANG   : en_US.UTF-8
TERM   : tmux-256color

GOOS    : darwin
GOARCH  : amd64
Compiler: gc
NumCPU  : 16

panic: terminal entry not found [recovered]
        panic: terminal entry not found

Seems like theres a problem with some custom terminals...

How did you get that $TERM setting?

I just tried to just start tmux on my Mac, and I got "screen" as the $TERM value, which worked fine.

So do you have any repro steps?

I'm actually setting that in my .tmux.conf file. I think it was for a workaround with italics not working in NeoVim. I believe these are the relevant lines:

set -g default-terminal "tmux-256color"
set -ga terminal-overrides ',xterm-256color:Tc'

Thanks for the background @garymh!

Digging a bit this turns out to have been reported in https://github.com/gdamore/tcell/issues/245, please add yourself to that ticket.

I'm using Tcell for drawing on the terminal (it's super nice!), and when they start supporting this I will as well.

I note also (to my surprise) that less doesn't work with tmux-256color either.

@walles just a heads up that at least for me less works as expected with TERM set to tmux-256color (provided the appropriate terminfo entry is installed)
